1B Mobile Users Vulnerable to Ongoing 'SimJacker' Surveillance Attack
More than one billion mobile users are at risk from a SIM card flaw being currently exploited by threat actors, researchers warn.
A vulnerability discovered in mobile SIM cards is being actively exploited to track phone owners’ locations, intercept calls and more – all merely by sending an SMS message to victims, researchers say.
Researchers on Thursday disclosed what they said is a widespread, ongoing exploit of a SIM card-based vulnerability, dubbed “SimJacker.” The glitch has been exploited for the past two years by “a specific private company that works with governments to monitor individuals,” and impacts several mobile operators – with the potential to impact over a billion mobile phone users globally, according to by researchers with AdaptiveMobile Security.
“Simjacker has been further exploited to perform many other types of attacks against individuals and mobile operators such as fraud, scam calls, information leakage, denial of service and espionage,” said researchers with AdaptiveMobile Security in a post breaking down the attack, released Thursday.
They said they “observed the hackers vary their attacks, testing many of these further exploits. In theory, all makes and models of mobile phone are open to attack as the vulnerability is linked to a technology embedded on SIM cards.”
The attack stems from a technology in SIM cards called S@T Browser (short for SIMalliance Toolbox Browser). This technology, which is typically used for browsing through the SIM card, can be used for an array of functions such as opening browsers on the phone as well as other functions like setting up calls, playing ring tones and more.

Is the article helpful enough to identify if a particular SIM card is vulnerable, and/or has been compromised?

Lazy and probably accurate answer: assume yes. If not, you're being shafted in many other ways anyway with your cellphone. So yes.

Oh, c'mon, the scare-bar only claims one billion vulnerable, out of what, like five billion SIM cards in use worldwide? And, actually compromised, that's going to be even less.

That's still 1 out of 5 or 20% of all SIM cards. Is this an old bug or a current "feature"?
From the linked article:
So, it sounds like it's not terrible. Still, if you'd have reason to be worried about the authorities in any given nation you're visiting. I would highly recommend getting a burner phone for said country or something. Better yet, don't visit said country.
